✶ We have completed our transcription of the Hebrew pages of Seder Tefilot K’Minhag K.K. Sefaradim (Yosef Nachmuli 1885), a Greek-Sefaradi siddur from the island of Corfu. If you can read and type in Greek, don’t miss your opportunity to work on transcribing the Greek translation ,

Do you like your siddur Open or Closed?

The Open Siddur is a volunteer-driven, non-profit, non-denominational, and non-prescriptive community project growing a gratis and libré Open Access archive of Jewish prayer, liturgy, and related works (historic and contemporary, familiar and obscure), composed in every era, region, and language Jews have ever prayed. Our goal is to provide a platform for sharing open-source resources, tools, and content for individuals and communities crafting their own prayerbook (siddur). Through this we hope to empower personal autonomy, to preserve customs, and to foster openness and vitality in religious culture. ☞ Read more about our mission, vision, and project history.

In addition to text that we carefully transcribe and proofread from works in the Public Domain, our community of contributors make their own copyrighted work available for your adaptive reuse under their choice of Open Content license. We posit that the resources and technologies necessary to engage in the most fundamental activities of Judaism be accessible, gratis (without cost) and libré (without restriction), for all its voluntary participants and educators. Thus, we believe that everyone engaged in the practice of Jewish prayer should be empowered to craft their own prayerbooks with open-source publishing technologies and open content licensed prayers (and not be limited by proprietary technologies or content). One committed at heart to the craft of their own prayerbook should really only be limited by their knowledge of prayers and liturgical customs.

We envision a world where prayerbooks are not only treated as containers of Jewish identity and spiritual heritage, but also as open-source repositories of effective exercises, prompts, and methods – shared praxes – for growing the creative and emotional intelligence in the individuals and communities who choose to utilize them in their committed practice. Our commitment to collaboration and sharing is why we call our siddur project 'OPEN.' We aspire to be a resource of Jewish prayer as freely shared as the Torah of Kindness (תּוֹרָת חֶסֶד) described in Sukkah 49b, transmitted as openly and earnestly as the Torah was shared in the Midbar Sinai, as free a resource for all who enter into the world as fire, water, and wilderness (cf. Mekhilta d'Rebbi Yishmael on Shemot 20:2, §Baḥodesh). Just as the otherwise ephemeral world of scholarship and creativity is sustained by the acknowledgment implicit in proper credit and attribution, so too is the vitality of this heartfelt collective. All these offerings of words, insight, and ritual praxis graciously shared by those "whose hearts have been stirred" (cf. Exodus 36:2) have been made with the expectation of attribution as explicitly stated in the rabbinic Jewish requirement concerning the proper transmission of oral teachings: they must be shared in the name of the one from whom they were received (cf. Avot 6:6, Megillah 15a:20). In this way, the lineage of the source is preserved, the creator is honored, and the lattice of kindness supporting the selfless creative act is reinforced.
